- Ml FGm/Z C4776 ATTORNEYS Patented May 20, 19336 UNITED STATES PATENT OFFICE JAMES G. COLLINS, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO ATLAS PRESS COIFPANY, 0F KALAMAZOO, MICHIGAN v j SPANNER WRENCH Application filed October 8, 1928. Serial No. 310,971.

The objects of the invention are:

First, to provide a spanner wrench which is quickly and conveniently adjusted for use.

Second, to provide improved adjusting jaws for such a wrench.

Third, to provide an improved adjusting slide for the jaw.

Objects pertaining to details and economies of construction and operation will definitely appear from the detailed description to follow. The invention is defined in the claims.

A preferred embodiment of my invention is illustrated in the accompanying drawing, in which: I V

Fig. 1 is substantially a full size side elevation view of my improved spanner wrench,

the dotted lines indicating closed position of adjustment.

Fig. 2 is an elevation view from the right hand of Fig. 1, part of the handle being broken away. v

Fig. 3 is a detail sectional elevation on line 33 of Fig. 2 showing the wrench in its closed position. 7

The parts will be identified by their numerals of reference which are the same in all the views. j

1 is the wrench handle terminating in a screw driver or other suitable tool below. 2 is the fixed jaw slightly curved and terminating in a' spanner wrench tooth 21. 22 is the engaging side pin for use as a face spanner. 3 is the movable jaw pivoted to the handle at 31 and having a laterally projecting engaging pin 32 to cooperate with the pin 22 on the fixed jaw when used as a face spanner.

- 4 is the adjusting slide which controls the pivoted jaw. 5 is the connecting link from the slide 4: to the jaw 3 pivoted to the jaw at 51 and to the slide at 52. The link 5'is pro.

vided with serrations or teeth 53v at its lower end which correspond to serrations 11 on the side of the handle 1 with which they cooperate and engage when the wrench is adjusted.

The slide 4. is provided with a spring 11 folded upon itself and with its ends engaging the slide at each side and formed like a shoe at 42 to slide on the handle and yieldingly back of theslide 4 and between the ends 42 of the spring 41 by which the jaw may be securely clamped after it has been adjusted.-

The spring merely. yields to facilitate adjustment of the structure which may be locked during use. The structure operates fairly well without the locking screw but is made very positive when the said screw is clamped down. The operation is very clear from the description and an examination of the draw mg.

I desire to claim my invention specifically as illustrated and also broadly as pointed out in the appended claims.

7 Having thus described my invention, what I claim as new and desireto secure by Letters Patent, is V 1. In a spanner wrench, a handle termimating in a fixed aw with suitable engaging hook, a laterally projecting engaging pin at the side of the jaw,- a movable jaw pivoted to the handle and having a laterally projecting engaging pin corresponding to the engaging pin on the fixed jaw, a slide on the handle consisting of a loop, a connecting link from the slide to the movable jaw whereby the same is adjusted by the adjustment of the slide, teeth on the side of the handle, teeth on the end of the connecting link 00- back ofthe said spring to lock the same in place, as specified.

2. In a spanner wrench, a handle terminating in a fixed aw, a laterally projecting engaging pin at the side of the jaw, a movable jaw pivoted to the handle and having a laterally projecting engaging pin corresponding to the engaging pin on the fixed jaw, a slide on the handle consisting of a loop, a connecting link from the slide to the movable jaw whereby the same is adjusted by the adjustment of the slide, teeth on the side of the handle, teeth on the end of the connecting link cooperating therewith, a spring for the slide doubled on itself and its ends engaging the slide to hold the said teeth yieldingly in engagement, a set screw in said slide disposed between the recurved ends of and against the back of the said spring to lock the same in place, as specified.

3. In a spanner wrench, a handle terminating in a fixed jaw, a laterally projecting engaging pin at the side of the jaw, a movable jaw pivoted to the handle and having a laterally projecting engaging pin corresponding to the engaging pm on the fixed jaw, a slide on the handle consisting of a loop, a connecting link from the slide to the movable jaw whereby the same is adjusted by the adjustment of the slide, teeth on the side of the handle, teeth on the end of the connecting link cooperating therewith, a spring for the slide doubled on itself and its ends engaging the slide to hold the said teeth yieldingly in engagement, as specified.

4. In a spanner wrench, a handle terminating in a fixed jaw, a laterally projecting engaging pin at the side of the jaw, a movable jaw pivoted to the handle and having a laterally projecting engaging pin corresponding to the engaging pin on the fixed jaw, a slide on the handle consisting of a loop, a connecting link from the slide to the movable jaw whereby the same is adjusted by the adjustment of the slide, teeth on the side of the handle, teeth on the end of the connecting link cooperating therewith, a set screw in said slide to lock the same in place, as specified.

In witness whereof I have hereunto set my hand.

JAMES G. COLLINS.
